Should we add the following example as test cases the test suite, making explicit that the behavior is not dictated by the spec?
Can someone remind me how/whether we have dealt with test cases that allow - implementation dependent -  alternative outcomes? 
I think I vaguely remember that we had that case already...

Graph store:
   <g1> 
     _:a :p :o .
   
Do we want Q1
 
   INSERT {GRAPH <g1> ?s :p :o2 } WHERE  {GRAPH <g1> ?s :p :o } 

and Q2

   INSERT {GRAPH <g1> ?s  :p :o2 } USING <g1> WHERE  {?s :p :o } 
 
and Q3

   INSERT {GRAPH <g1> ?s  :p :o2 } USING NAMED <g1> WHERE  {GRAPH <g1> ?s  :p :o } 

behave the same or different? That is, does the new dataset defined by USING/USING NAMED change bnodes or not?

Essentially, for Q1, we'd expect as resulting graph store:

   <g1> 
     _:a :p :o; :o2.

whereas for Q2/Q3 we probably may rather expect:

   <g1> 
     _:a :p :o. 
     _:b :p :o2.

but that might be implementation depenent also 

   <g1> 
     _:a :p :o; :o2.
